“It’s a Wrap” in Northern Areas

Sightings along the Great Lakes have dwindled. Only a few late migrants are being reported along the Atlantic Coast. 

From the Tip at Point Pelee National Park: Journey North citizen scientist, Darlene Burgess, provided this report: “After a few days of very strong westerly wind stalling the Monarch Migration…No Monarchs seen except one that arrived from the north at around 5:30 pm…Fri Oct 25th will again be a good migration day with light northerly wind. Temps decreasing to 11-13°c for the weekend again with strong wind. It’s a wrap for the season here at Point Pelee National Park!” (10/24/2019)

From Ocean Beach NY: Ellen noted, “25 Late flyers came in yesterday, mild north winds, 65 degrees, they were very thirsty. Nectar is as important as milkweed! Plant, plant, plant! Helps them fly, fly, fly!” (10/24/2019)

Fall Roosts In Mexico

From Santa Catarina, NLE: Elsa commented, “Correo Real group reported strong flow of monarchs in Santa Catarina, N.L. so in the afternoon we went to see them at the Huasteca Canyon. There were butterflies flying very high and others flying very low, and to our surprise at 5:00 pm we found a patch of 6 trees with fall roost, they were mesquites (Prosopis glandulosa), anacahuitas (Cordia boissieri), granjenos (Celtis pallida) and others, in a place more or less protected from the strong wind of the Canyon. Hard to calculate the amount, I think it was probably around 2000.” (10/28/2019)
